Can't fault Milltek TBH. The manifold has been on my car for 40k and was second hand from anouther chap who did about 5k on it. Its been good for the money I paid for it. It was only a matter of time, given the power and heat and flames that my car puts down there that something would give up the ghost. Easy fix though for £50 + labour and it'll be spot on for a none big valve head
JCW or GP or 15-17% pullied car for the track and strip.
